Now Keane has replied to Ferguson’s jibes in an interview with the Sunday Times reporter David Walsh.

Keane told the Sunday Times: “If you want to question my managerial record, listen, you could question every pundit’s managerial skill in relation to Ferguson’s and we’re all going to come up short.

“But I would also say that without players like myself, maybe he wouldn’t have such a good managerial record because players who go down the punditry road, it’s soon forgotten that we put bodies on the line for him.”

“People say he stood by me in difficult times,” added Keane.

“But he didn’t when I was 34, not when I was towards the end and had a few differences with his assistant Carlos Queiroz. All of a sudden then it was off you go, Roy, and here’s the statement we’ve done.”
